This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

It's still not earning you money to spend electricity because you still have to pay the transfer fee which is around 6 cents / kWh but it's pretty damn cheap nevertheless, mostly because of the excess in wind energy.

Last winter because of a mistake it dropped down to negative 50 cents / kWh for few hours, averaging negative 20 cents for the entire day. People were literally earning money by spending electricity. Some were running electric heaters outside in the middle of the winter.

Renewables dipped below $0 for us in California too this year. Fortunately for the utilities, those savings don't get passed along to customers and I still paid $0.53 kW/h. /s

Lucky you.

That is surprisingly expensive, it's more than here (Cambodia), which is notoriously high for the region at around 20c.

If you want people to use less energy this is the only way

[–] [email protected] 14 points 7 months ago (4 children)

Alternative: Create more energy, preferably renewable. Penalize heavy users only (raise costs). Incentivize (lower costs) those using renewables like solar panels. Raising costs for all is the laziest way.

In the case of PG&E, they have to pay for killing a bunch of people and burning down some towns, so they're passing the expenses onto everyone else. Privatize the gains and socialize the losses baybeee. Gotta love state sanctioned monopolies.

Why /s there?

Also fuck PG&E. Fuck that company. Assholes.

Why does it feel like every Nordic country is much better then Sweden these days.

[–] [email protected] 40 points 7 months ago

We each have our problems but I have to admit that I haven't heard many positive news coming from there recently.

[–] [email protected] 21 points 7 months ago

The energy prices in Sweden were also mostly negative yesterday, and today as well. Although probably not quite as much as in Finland.

Resistive load. Gotta dump excess energy somewhere.

My electric company here in the us mines bitcoin with it and charges us a "peak time incentive" pricing model.

Sometimes I wonder what it would have been like to be born somewhere like Finland.

Colder and darker for sure

Only for half a year. The other half is colder and brighter!

This is not a good thing. Any time generation has to pay to produce, solar and wind rollouts are slowed.

We need better demand shaping methods, to increase load on grids during periods of excess production, and decrease loads during shortages. We need to stabilize rates at profitable points to maintain growth of green energy projects.

We also need long-term grid storage methods, to reduce seasonal variation. A given solar project will produce more than twice as much power during a long summer day as it will during a short winter day. If we build enough solar to meet our needs during October and March, we will have shortages in November, January, February, and surpluses from April through September. We will need some sort of thermal production capability anyway; hydrogen electrolysis or Fischer-Tropsch synfuel production can soak up that surplus generation capacity and produce green, carbon-free or carbon-neutral, storable fuels for thermal generation and/or the transportation sector.

Negative pricing IS a demand shaping method, you need to have a certain % of the electricity produced that is consumed at the same time, otherwise you risk having an unstable electricity grid.

Or just export it - there must be nearby counties that don't have such a good renewable electric situation.

[–] [email protected] 9 points 7 months ago (1 children)

"just export it" sounds so simple, but the required infrastructure is actually incredibly expensive. Also most of Europe is already pretty tightly connected and trade does happen to a significant degree, but I have no idea what the actual percentage is or if it's used to balance oversupply and/or shortages. Kinda hard to find reliable sources for that.

Meanwhile in the USA the electric companies will mine BTC, and charge consumers more wherever they can. They will even sue people for going solar for "losing out on profits".

[–] [email protected] 26 points 7 months ago (2 children)

Luckily my energy company found a way around all of this to always charge more! We have "Basic Customer Charge", "Summary of Rider Adjustments", "Renewable Energy Rider", and then Sales Tax on all of it. My base charge is over 100$ before they start calculating your actually energy usage. Yay electrical monopolies!

Welcome to the world of renewables. We have quite some negative hours in Germany in summer when sun and wind are active simultaneously. Unfortunately Finland relies on nuclear, does it?

[–] [email protected] 63 points 7 months ago (4 children)

What's wrong with nuclear?

[–] [email protected] 42 points 7 months ago

People still buying into oil company FUD from the 70s

[–] [email protected] 22 points 7 months ago (3 children)

The toxic and deadly trash it makes. Deadly for centuries.

In Germany we still search for an area to dig for ages. We search since 30 years.

[–] [email protected] 50 points 7 months ago (17 children)

In the mean time, you seem to be a big fan of burning coal instead, which only pollutes the atmosphere instead of easily storable material to be buried when we feel we have found a sufficient deep hole that no one is going to look in.

Most nuclear waste issues are vastly over-exaggerated. Most of the nuclear waste is not long term waste. It's not things like spent fuel rods, it's things like safety equipment and gear. Those aren't highly contaminated, and much of it can almost be thrown away in regular landfills. The middle range of materials are almost always kept on site through the entire life of the nuclear plant. Through the lifetime of the plant that material will naturally decay away and by the time the plant is decommissioned only a fraction will be left to handle storage for a while longer from the most recent years.

Nuclear waste can be divided into four different types:

  1. Very low-level waste: Waste suitable for near-surface landfills, requiring lower containment and isolation.
  2. Low-level waste: Waste needing robust containment for up to a few hundred years, suitable for disposal in engineered near-surface facilities.
  3. Intermediate-level waste: Waste that requires a greater degree of containment and isolation than that provided by near-surface disposal.
  4. High-level waste: Waste is disposed of in deep, stable geological formations, typically several hundred meters below the surface.

Despite safety concerns, high-level radioactive waste constitutes less than 0.25% of total radioactive waste reported to the IAEA.
These numbers are worldwide for the last 4 years:

Many active reactors rely on old designs, we have new ones now that are far cleaner. Some even use existing waste as fuel, so we would be able to get rid of those old stock piles.

Ofc the oil industry is fighting that tooth and nail since it doesn't jive with their FUD campaign

[–] [email protected] 11 points 7 months ago (1 children)

Not only doesn't it follow their FUD, but their existing business cannot easily transition to it since the entire process is completely different. Oil, coal, and natural gas are all fairly similar from their perspective.

It's a poor solution for what people like to call "baseline power".

The argument goes: solar and wind don't provide consistent power, so there has to be some power generation that doesn't fluctuate so we always have X amount of power to make up for when solar/wind don't suffice. Nuclear is consistent and high-output, so it's perfect for this.

Unfortunately, reality is a little different. First problem is that solar/wind at scale don't fluctuate as much. The sun always shines somewhere, and the wind always blows somewhere. You have to aggregate a large area together, but that already exists with the European energy market.

Second issue is that solar/wind at scale regularly (or will regularly) produce more than 100% of the demand. This gives you two options: either spend the excess energy, or stop generating so much of it. Spending the excess requires negative energy prices so people will use it, causing profitability issues for large power plants. As nuclear is one of the most expensive sources of energy, this requires hefty subsidies which need to be paid for by taxpayers. The alternative is shutting the power plant down, but nuclear plants in particular aren't able to quickly shut off and on on demand. And as long as they're not turned on they're losing money, again requiring hefty subsidies. You could try turning off renewable power generation, but that just causes energy prices to rise due to a forced market intervention. Basically, unless your baseline power generator is able to switch off and on easily and can economically survive a bit of downtime, it's not very viable.

Nuclear is safe. It produces a lot of power, the waste problem is perfectly manageable and the tech has that cool-factor. But with the rapid rise of solar and wind, which are becoming cheaper every day, it's economic viability is under strong pressure. It just costs too much, and all that money could have been spent investing into clean and above all cheap energy instead. I used to be pro-nuclear, but after seeing the actual cost calculations for these things I think it's not worth doing at the moment.

As for what I think a good baseline power source would be: I think we have to settle for (bio-)gas. It's super quick to turn off and on and still fairly cheap. And certainly not as polluting as coal. We keep the gas generators open until we have enough solar/wind/battery/hydrogen going, as backup. If nuclear gets some kind of breakthrough that allows them to be cheaper then great! Until then we should use the better solutions we have available right now (and no, SMRs are not the breakthrough you might think it is. They're still massively more expensive than the alternatives and so far have not really managed to reduce either costs or buils times by any significant margin).

Maybe fusion in the future manages to be economically viable. Fingers crossed!

Look at the clean-up cost of Fukushima, it's mental. Then look at the set-up costs, and how long it takes. Compare that to renewables.

[–] [email protected] 11 points 7 months ago (3 children)

Look at costs of dam failures. Or how many people they killed. Or look at the cost of climate change. Fukushima is nothing in comparison. You can also compare it to the cost of the tsunami that actually caused the issue to begin with.

Yeah we though relying on Russian natural gas might pose some issues in the future so we went with nuclear instead. I hope we build more of it.

[–] [email protected] 25 points 7 months ago (4 children)

I know nuclear isn't ideal but to rule it out completely while the alternative for stable baseline power is still coal and gas seems problematic to me

Shutting down their nuclear power plants is probably the worst thing the Germans have done.

It might be cheap now, but I'm fearing the December - February i.e. the coldest part of the year when the price can get salty. Especially when/if the OL3 (or any other) plant trips offline, the price will bump up a lot.

The good part of having excess eletricity is that doing a "electric-kettle" district heating becomes feasible. So instead of reducing the (windmill) production, it makes sense to dump the excess generation capacity into district-heating. (which has large capacity to store the heat)

This will hopefully lead to storage methods, maybe exportable ones like hydrogen

[–] [email protected] 30 points 7 months ago* (last edited 7 months ago) (9 children)

Hydrogen is not good for energy storage. Round trip efficiency is abysmal and its incredibly difficult to store in the first place
